tThe invention is especially concerned with.

a perforator adapted and arranged for perforating tape for automatic printing telegraph `systems employing a code of the Baudot type in which'each character comprises a definite numberof impulses, usually five or six, the message holes for each character being punched in a single row transversely of the tape, although it is to be understood that the invention is not limitedthereto, but may be employedwith a Morse or other type of code.

hole punch pins have been arran ed-in a sin- -gl'e transverse row and the ,fee .wheel has necessarily been placed following the` Yflinch ing position, that is. between the-punc Ipins -and the tape transmitter so as to drawthe tape through the lpunch block'.;v This causes4 an. appreciable length of the perforated tape 'to intervene between the punch pins of the perforator and the transmitter, -resulting in a corresponding lag in the transmissionof the signals.l

One of the objects of this invention is to reduce to aminimum this time lag between v the perforatingJof the tape and the transmission of the corresponding signals.

Another object is to provide aftape perforator of such construction that the inlet 'of the associated tape transmitter may7` be placed closely adjacent the punching position of the perforator. c

Anotherobject is to reduce the amount of -Other objects'andadvantages of the invention willappear from theffollowingldef to t e construction of the punch 'In tape perforators, as. heretofore constructed, the code punch pins andthe feed associated vwith a tape transmitter -hole punch; tape lntervenlng between the polnt vof perforating and the point of transmitting.

scription taken in connection with the accompanyingvdrawings and appended claims. fIn accordance with our invention we position the code punches ad'acent the outer edge of the punch block an locate the feed hole punch forward thereof with lthe feed lWheel intermediate the' feed hole punch and the code punches so as tcpuf'sh the tape past the code perforating` osition',"l thejpunch block being disposed re ativ'e to the remaining mechanism of the perforator' so that a tape transmitter may abut against the punch block'with the tape inlet ofthe transmitterl close to the unching position of lthe per-v forator where y only a short length of rl forated tape, corresponding to a few. c aracters will intervenebetweeni the perfcrator and thel tape transmitter.- 4

The invention further resides in the special construction and arrangement of the lparts of the'perforator and transmitter as willapf f -ear more fully from" the'accompanylng rawings in which: y f' Figure 1 is a sideelevalon of a reperfor-'v lol'md tape in .tefizo F1 re 2 1s a plan view of the reperforator,

We have illustrated the invention as. ap- 'plied to a reperforator which responds to line signals received over a multip ex channel for producing a perforatedtape for use in transmission over another multiplex circuit, butit is to be understood that the invention is not .so limited. It is equally,- aplicable to start-stop simplex. reperforators, Ee -board perforators and the like.

e supporting structure for `the reperfo-c rator comprises a base plate 10 and a vertical partition plate 11 carried thereby. The reperforatinn mechanism is supported' from one side of the partition plate and consists in general of a punch block 12 mounted upon the plate by screws 13 and having a group of six code punch pins 14 and a feed hole punch pin 15, a punch hammer 16, pivoted at 17 for operating the punch pins, a ,groupv of interponent bars 18 adapted to be shifted beneath the code punch pinsto determine ing disposed at the .forwa the selection thereof, selecting solenoids 19 for actuatinV the. ,interponent bars, punch solenoids 20 oroperating the punch hammer 16 and a tape feed ro'11er21 '(Figure 3) disposed between the pins 14 and 15 and actuated on movement of the punch hammer, through a pawl 22. The tape 24 extends from a suitable reel 25. over a tensioning lever 26, pivoted at 27v and rovided with a tensioning yspring 28, and t ence apross the` to of the punch block 12. s

e particular punch block illustrated is provided with punches of such number .and arrangement as to adapt the perforator for use in perforating tape forautomatic telegra h systems .employing a code wherein eacli) character ycomprises six impulses, although obviouslytlie number of punches and the number of units of the code mayfbe vii-l ried. `In the form shown it comprises the six code unches 14 andthe feed hole punch. 1,5, this lyatter punch being of smaller diameter than the remainin punches and bei end of the punch block 12, the code punches beiigdisposedl adozent the oppositeI edge of 'the punch bl Each of the code punches has an annulareollar 29 normally resting on the lower wall of the punch block, the punches extending downwardly through the lower wall and upwardly through openings in a retracting block 30 and through openings inthe top of the punch block. `The punches are normally retained in a lowered position by spiral springs 31 surrounding certain of the punch pins and acting upon the retracting block which is guided on fixed vertical posts 32. A die plate 33 is provided with openings in alignment with the punch pins. of the punch block is groovedl at 34 'for the The top passa e of the tape between the die plate and t e to of the punch pins. I i

The fee hole pin 15 is also provided with a collar 3 5 resting on the bottomV wall of the punch block, the. pin extending upwardly through an opening .in a retracting block 36 which is gui ed on fixed posts 37 (Fig. 6) extending between the upper and lower walls of the block. The pin 15 extends through the top wall of the punch block in alignment with an opening 38 in the die plate 39 and is surrounded by compression, s ring 40 which normally maintains it in its ower position. y

Since the feed holes have to be punched for every character and also for blank portions ofthe tape, the punch 15 is made longer than the code punches 14 so that it will always be actuated by the hammer- 16. The code punches 14 are shorter than the punch 15 so that the hammer cannot force them through the tape unless the ends of the corresponding interponent members 18 are interposed beneath the punch pins.

yThe six interponent members are pivoted at the ends opposite the punch pins 14, to bell crank levers 41, ivoted in turn at 42 to the `tops of the selecting solenoids 19 and having The selecting solenoids are mounted upon a shelf 44 carried by the partition plate 11.

The plungers 45 and 46 of the punch solenoids 20 are secured to a cross bar 47 having a vertical push rod 48 resting a ainst the lower side of the hammer 16, to e evate the ysame against the tension of a spiral spring .49, to raise the interponent bars, which have .been shifted, against the message punchpins to forcev theA same u wardly through the tape.`k

The hammer 16 iiec'tl engages the feed hole punchv15 to punch t e feed holes.

They feed roller 21 is 'ournaled in the side walls of the unch bloc in bearin'gs 50 and 51 and its. re uced shaft 52 extends throu h the partition plate 11 and is provided on t e opposite side thereof with a ratchet wheel .53 adapted to be. engaged by jockey roller 54 carried by a ivoted lever 55 and held in engagement wit the ratchet wheel by a spring 56. The feed roller is provided with a circumferential row of radial pins 57 which engage the central feed openingof the tape to push the tape across the code punch pins. The vpawl-22, ivoted to the punch hammer at 58, is held y a spring 59 in engagement with ratchet teeth 60 formed in the feed roller 21. The pawl 15-ispsitioned in one of the ratchet teeth uson the upward movement of thehammer an serves to rotate the feed wheel one space on the return movement of the hammer.

The tape is held engagemnt with the ics lll)

and 39 bya'V -plate`61 hinged at 62 and provided at its opposite edge with a thumb latch 63 s 4 It will be noted that the code pins 14 are disposed close to the edge of the punch block, an that the punch block is disposed with its outlet side at the extreme right-hand side of the Derforating mechanism, as shown vin Fi gure 1, thus permitting the tapetransmitter, mf indicated generally as 65, to abut directly against the edge of the punch block-with the ta'veinlet 66 of the transmitter close to the code hole perforating position, yso that only a few characters intervene in thetape be- 15 tween the perforating position and the inlet of the tape transmitter. The 'transmitting or contact control pins 67 of the tape transmitter ma abutting side of the transmitter so that the tape will travel only a short distance in the transmitter before comin into transmitting position. The tape is rawn through the tape transmitter b a feed wheel 68, against which the tape is eld bv a plate 69 hinged h `at70. The operating mechanism of the tape transmitter may be o the .construction shown in patent to G. R. Benjamin, No. 1,298,440,

granted March 25, 1919.

In order to enable theo transmitter to be interrupte when the perforator lags behind the transmitter, an autocontrol mechanism may be provided. As shown, this mec anism comprises a rod 72 extendin over thertape in a V-groove formed bly bevehng the abuttin ends 73 and 74 -of t 'e punch block and t e tape transmitter.

The rod 72 is pivoted at 75 and has a cam 76 adapted when the rod is lifted by tightening of the'tape, to permit contacts 77 to'` o n, to interrupt the operating circuit (not own) of thetape transmitter.

It is obvious, of course, that numerous changes and modifications maybe made in "the construction and arrangement of the parts and other means may be provided for accomplishing` the 'same objects, and, therefore, 4we do not desire to be limited .to the exactdetails shown and described except in accordance with .the appended claims.
